On an expedition to a barren land that had witnessed volcanic activity, geologists noticed heavy lichen growth on some of the hard lava. in other areas, lichens were replaced by grasses. after many years, the geologists expect to find the area filled with full-grown hardwood trees, grasses, and shrubs. what is this process called?
a. succession
b. mutualism
c. competition

d.

explanation:

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
